@josesebas1990 from what I understand you should be able to use both and alternate between them by software, but probably not use them at the same time (e.g. listen or receive on both antennas at the same time).

@lora Hi, lopy4 use sx1276 semtech radio that can only do fsk,gfsk,msk,gmsk,ook and lora modulation. So i suppose for using ASK you need an external modem and use UART RX/TX.

@robert-hh said in Lopy4 433MHz: @bmarkus Standard build of Pycom. You know that I made a version of the pycom firmware and tested that against LORIOT. It worked. I see, thanks. I was not sure your are referring to the LoRa Alliance or PyCom

Hi @prawnhead You just need an antenna for the frequency you need

@bmarkus Hello Bèla. I now tested OTAA join. Due to the timing jitter of the gateway, I wanted to use RX2 for the join response. So Ive set that in the device parameters of the Loriot server. But that did not work. The join response appeared in the RX1 window. Did I expected something wrong from the settings, or just looked at the wrong place? P.S.: After a few attempts, join also worked at the RX1 window.

@jmarcelino Aha! This is excellent, thanks for pointing me in the right direction.
